The overall shape looks spot-on Al...very good job so far.
Question: I would like to try using urethane foam as a buck for vacu-forming...any tip you could give me would be helpfull (any releasing agent I have to use on the foam, or do I have to use bondo to make the buck stronger)? Any help would be appreciated.
Thanks.

Thanks.

to use the foam for a buck for forming, first make sure your foam is at least 5 lb density. as for a release., make sure you get the foam as close to the shape you want, i would suggest if its spot on just primer it and sand smooth with 400 or finer, then you can dust it with baby powder or a thin coat of vaseline for a release.

i try not to add to much bondo if i dont have to. also it depends on how many pulls you are going to have to make. if you have any other question feel free to PM me.

Started hogging out the foam to fit the cockpit under the cone. still needs a little sanding but its getting there. also finish the underside details and add the plate and panel lines,and window moldings. but its getting there.

Been awhile. but heres what i have so far. added the window moldings, which was a big pain in the butt. next i will add the plating and panel lines. then i will move onto the scorpion tail. after that should be all down hill.
